ELEGTHlC lNSLEc Specification of Letters Faten't.

Patented Feb. 5, 1907.

Application filed February 7,1996. Serial lla. 299,992.

Be it known that l, Hnxnr O. (IAN Een, a citizen ot the United States,residing att-Sgr: euse, in the countjj' ol Onondaga and State r New York, have invented new and useful niprovenients in Electric lnsoles, ot which j the following is a specilieation.

This invention relates to electric insoles for shoes el the tvpe disclosed in Patent No 647,647 granted to ine April 1.7, i900.

The present invention has toi' its objects E to provide a simple inexpensive device oi this character which in practico will a'l'ord a firm support :For the instep-arch, one wherebj suitable voltaic currents will be generated through the feet and lii'nbs 'lor relievii'ig rheumatic and other pains, and one whereby' a yieldable support will be allorded lor the hecl of the wearer.

l/Vith these and other objects in. view the invention coniprises the novel Yfeatures oi con- 3 struction and combination of parts more i'ullv hereinafter described.

In the accompanying drawings, E is a top plan view oit an insole embed" g i invention. Fig. 2 is central longitudinal l section through the sole, showing/ the saine j re l. uw' the j applied to a shoe. F 3 is a vertical crosssection taken on the line 3 3 of Fig. l. Referring to the drawiiiigs, l i csignates a base-plate composed et sj'iring-steel and hav- 1 ing applied to its norifialljiupper Ylace an.y electric or galvanie couple comprising a Zinc g plate 2 and a copper plate B, in turn applied i to the upper face ol' the plate 2 and forming a covering therefor, there being provided in l the plate 3 a pair of elongated openings #l and 5, disposed, respectively', adjacent opposite j ends ot the insole and adapted to rece Ye opposite projections t3 7, sti-ucl; or pressed -trono the plate 2 during the Vl'oiication thereof, Wherelo.v the portions G 7 ot the zinc plate are exposed within the plane et the copper plate. l l Applied to the normally upper 'tace ot the j insole and for partially coveringl the tace elf i plate 3 is a felt or other suitable absorbent pad 8, secured to the insole bji i? aus oi a central fastening ineinber or rivet 9, which serves to connect the plates l, 2, and $3 at the center ol' the sole, the said plates being connected at the forward end et the sole by l means oll a 'fastening :member or 'rivet lt), l While the plates 2 and 3 are united at the heel l' end of the sole by means ot a Vfastening ineinsuri'ace ot the copper plate o j ber or rivet 11, it being noted that the rear 1 portion olE the duplex plate or couple 2 3 is wholly 'l'iee 'trein engagement with the plate l and is adapted to spring or )field relatively thereto Yfor iuparting the requisite amount o'l elasticity to the heel portion ol the device.

',lfhc insole is curved upwardly along one edge, as at l2, to properly support the adjacent or inner side of the toot, the sole being properly shaped to 'lit the bottoni ol the foot.

ln practice the sole is placed within the shoe and the moisture ot the loot acting on passes through the toot and limbs and serves to eliminato the uric acid iroin the blood, thus curing rheumatic or other pains, the acid and perspiration which is l'rccd through the voltaic action being absorbed by the pad S, as will be readily ui'iderstood.

lt is to be particularly noted that in the use oi the device and owing to the portions t5 and 7 ot the Zinc being exposed within the the moisture may act more r nidily upon the plates in prod ucing t he electric currents, and i'urtlier, that the rear portion of the duplex plate serves 'to vieldably support the heel and a'flord a j cushioning action ol the latter during the action of walking.

llavin g thus l'ully described niy invention, what l claim isM i. In a device ot the class described, a sj'ning-metal lnise-plate, a voltaie couple applied Ythereto and rcomprising apair of c0- aciing ineial plates arranged one over the other, fastening members at the ends oi and vtor securing said plates together, and an intermediate Afastening member connecting the pla 'ics together and to the base-plate, the uppermost plate ot the couple having openings through which portions of' the underlying plate are exposed.

2. ln a device ol'- the class described, a metal base-plate, a voltaic couple applied thereto and comprising a pair of coacting metal plates arranged one over the other, a isiening member applied through the plates of the couple and the base-plate at the iorward end ol the latter, a second fastening member connecting the plates et the couple at thrir rear ends, a pad applied over the couple, and an intermediate 'fastening meinber extended through the base-plate, couple the uppermost plate of the couple having thereto for yieldabiy supporting the heel` ofy 1o openings through which portions of the unthe wearer. derlying plate are exposed. In testimony whereof I aHiX my signature 3. 11% a device of the ola-ss desorihedH in presence of two Witnesses. meta ase-plate, an e eotre coup e attac e( i thereto and comprising a pair of ooaotng v HENRY O' CAN DEE' metal plates, said couple having its rear por l Witnesses: tion Wholly free from engagement With the NATHAN ABELSON, base-plate and adapted to yield relative 1 l K.
